Abstract: The present disclosure provides an oral care composition and a preparation method, and an application thereof. The composition includes: a drug-loaded micelle, wherein the drug-loaded micelle includes a polymer micelle and an enamel restoration drug physically wrapped in the polymer micelle, and the polymer micelle is micelle particles formed by a water-soluble polymer with a structure shown by Formula I in an aqueous solution with presence of tannic acid and the micelle particles have a shell connected to a salivary protein polypeptide through chemical bonds. The oral care composition in the present disclosure enables the salivary protein polypeptide to adhere to the surfaces of teeth so as to open the borate ester bond between the tannic acid and the water-soluble polymer in an acidic environment generated by the dental caries and release the tannic acid and sodium fluoride, thus achieving the purpose of preventing dental caries and restoring tooth defects.

Abstract: The present invention provides an array substrate, which comprises a peripheral region and a plurality of conductive terminals disposed in the peripheral region. The peripheral region comprises a base substrate and a buffer layer, an insulating layer, and an interlayer dielectric layer orderly-overlapping disposed on the substrate. The array substrate further comprises grooves extending from the interlayer dielectric layer to the base substrate. Each of the conductive terminals comprises a first terminal, a crimping terminal which comprises a crimping layer and a second terminal disposed on the crimping layer, and a plurality of conductive particles. The first terminal comprises a connection section and an extension section, which is connected with the connection section. The second terminal is inserted into the groove. The conductive particles are uniformly sealed in a gap, so as to achieve the conduction between the first terminal and the second terminal.
